Explanation:

The best case scenario is that you pull 5 cards from the same suit in a row (eg: 5 spades in a row).  However, we have to plan for the worst case scenario that way we can guarantee to have 5 cards in one suit without having to look at the cards.

The worst case scenario is that you pull cards such that you get one suit at a time (eg: spade, heart, club, diamond). On the 5th draw, we finally get a card that repeats a suit.

If we repeat the sequence {spade, heart, club, diamond} in that order a total of two times, then we'll have 8 cards with 2 cards per suit.

Doing that sequence four times we'll have 4*4 = 16 cards and 4 cards per suit. That 17th card will repeat a suit a fifth time and this is when we'll be guaranteed to have at least 5 cards of one suit.

Answer:

The y -intercept of a graph is the point where the graph crosses the y -axis. (Because a function must pass the vertical line test , a function can have at most one y -intercept . ) The y -intercept is often referred to with just the y -value.

Step-by-step explanation:

Y - intercept represents the position of a point on y-axis or when a line passes through y-axis, it, actually, passes through a point on y-axis. And that point is called the y intercept. It is usually represented by and as a point, it is represented as.

It's called the "y intercept" and it's the y value of the point where the line intersects the y- axis. For this line, the y-intercept is "negative 1." You can find the y-intercept by looking at the graph and seeing which point crosses the y axis. This point will always have an x coordinate of zero.

Answer:

1. The scale factor here is 1.5

2. The scale factor here is 2/3

Step-by-step explanation:

Here, we shall be dealing with scales of triangles.

we have two triangles;

ABC and DEF

longest sides are in the ratio;

12 : 8

1. What scale factor translates DEF to ABC?

The ratio of the length can be beaten down to 3:2

So therefore, we can see that by multiplying the sides of of DEF by 1.5, we can arrive at the sides of ABC

So the scale factor here is 1.5

2. This is like the other way round of what we have above.

By multiplying the sides of ABC by 2/3, we shall have the sides of DEF

The equation is [tex]y = 6x -3[/tex].

Answer:

70

Step-by-step explanation:

The 7 is in the 10s place so its value would be 70

The 7 is in the tens place, so it represents 70

1379 = 1000 + 300 + 70 + 9

1379 = 1*1000 + 3*100 + 7*10 + 9*1

1379 = 1*10^3 + 3*10^2 + 7*10^1 + 9*10^0

the answer is 1/8

Step-by-step explanation:

2^-3= 1/2^3= 1/8

The term 2⁻³ can be written without an exponent will be 1/8.

In mathematics, integer exponents are exponents that should be integers. It may be a positive or negative number. In this situation, the positive integer exponents determine the number of times the base number should be multiplied by itself.

It is given that the given term is 2⁻³.

Any non-zero number raised to a negative power, according to the rule, equals its counterpart raised to the opposite positive power. In other words, an equation with a negative exponent is identical to the expression with a different exponent sign divided by 1.

=2⁻³

The following law of exponent is followed,

a⁻ⁿ=1/aⁿ

=2⁻³

=1/2³

1/8

Thus, the term 2⁻³ can be written without an exponent will be 1/8.

Answer:

1 x 4=4 (Both numbers are in the ones place, so their value are ones.)

Step-by-step explanation

In order to use place value to multiply, we use the distributive property to break apart each place. Always begin with the ones place. We can break apart a 2-digit by 1-digit number into 2 simpler problems. 1 x 4=4 (Both numbers are in the ones place, so their value are ones.)

This is about understanding Place Value.

An example of multiplication of two digit numbers has been done using Place value method.

For example, if we have a number to be 152, the place values are;

1 is 100; 5 is 50 and 2 is 2. This means that first number from the right is units, second from right is tens and third from right is hundreds.

3 is 30 and 7 remains 7.

If we want to add 47 + 52;

47 is; 40 and 7 while 52 is 50 and 2.

To add this, we will add the tens digit together and the units together to get; (40 + 50) + (7 + 2) = 99

47 is; 40 and 7 while 52 is 50 and 2.

Using the distributive property, we have;

(40 + 7) × (50 + 2)

⇒ 40(50) + 40(2) + 7(50) + 7(2)

⇒ 2000 + 80 + 350 + 14

⇒ 2444

Answer:

(a) Approximately 95% of women with platelet counts within 2 standard deviations of the​ mean.

(b) Approximately 99.7% of women have platelet counts between 65.2 and 431.8.

Step-by-step explanation:

The complete question is: The blood platelet counts of a group of women have a​ bell-shaped distribution with a mean of 248.5 and a standard deviation of 61.1. ​(All units are 1000 ​cells/mu​l.) using the empirical​ rule, find each approximate percentage below.

a. What is the approximate percentage of women with platelet counts within 2 standard deviations of the​ mean, or between 126.3 and 370.7​?

b. What is the approximate percentage of women with platelet counts between 65.2 and 431.8​?

We are given that the blood platelet counts of a group of women have a​ bell-shaped distribution with a mean of 248.5 and a standard deviation of 61.1.

Let X = the blood platelet counts of a group of women

The z-score probability distribution for the normal distribution is given by;

                             Z  =  [tex]\frac{X-\mu}{\sigma}[/tex]  ~ N(0,1)

where, [tex]\mu[/tex] = population mean = 248.5

            [tex]\sigma[/tex] = standard deviation = 61.1

Now, the empirical rule states that;

(a) The approximate percentage of women with platelet counts within 2 standard deviations of the​ mean, or between 126.3 and 370.7 is given by;

As we know that;

P([tex]\mu-2\sigma[/tex] < X < [tex]\mu+2\sigma[/tex]) = 0.95

P(248.5 - 2(61.1) < X < 248.5 + 2(61.1)) = 0.95

P(126.3 < X < 370.7) = 0.95

Hence, approximately 95% of women with platelet counts within 2 standard deviations of the​ mean.

(b) The approximate percentage of women with platelet counts between 65.2 and 431.8​ is given by;

Firstly, we will calculate the z-scores for both the counts;

z-score for 65.2 = [tex]\frac{X-\mu}{\sigma}[/tex]

                           = [tex]\frac{65.2-248.5}{61.1}[/tex] = -3

z-score for 431.8 = [tex]\frac{X-\mu}{\sigma}[/tex]

                           = [tex]\frac{431.8-248.5}{61.1}[/tex] = 3

This means that approximately 99.7% of women have platelet counts between 65.2 and 431.8.

The price for 2.5 pounds is $4.475

It is a method where we find the value of a single unit from the value of multiple units and the value of multiple units from the value of a single unit.

First, let us make a note of the information we have. There are 5 ice-creams. 5 ice-creams cost $125.

Step 1: Let’s find the cost of 1 ice cream. In order to do that, divide the total cost of ice-creams by the total number of ice-creams. The cost of 1 ice-cream = Total cost of ice-creams/Total number of ice-creams = 125/5 = 25. Therefore, the cost of 1 ice cream is $25.

Step 2: To find the cost of 3 ice-creams, multiply the cost of 1 ice cream by the number of ice-creams. The cost of 3 ice-creams is cost of 1 ice-cream × number of ice-creams = 25 × 3 = $75. Finally, we have the cost of 3 ice-creams i.e. $75.

Given:

price of one pound= $1.79

So, price of 2.5 pounds = $1.79 * 2.5

                                       = $4.475

Hence, the price for 2.5 pounds is $4.475.

Answer: y + 3x + 2 = 0

Step-by-step explanation:

The formula for that is

y - y₁

-------     = -3 where x₁ = -3, y₁ = 7

x - x₁

Therefore cross multiply and solve

y - 7 = -3[( x - (-3)]

y - 7 = -3( x + 3 )

y - 7 = -3x - 9

y + 3x -7 + 9 = 0

Answer:

x = 7/-p

Step-by-step explanation:

-(px - 2) = 9

-px + 2 = 9

-px = 7

x = [tex]-\frac{7}{p}[/tex]

Answer:

x = -7/p

Step-by-step explanation:

We have:

-(px - 2) = 9

Divide both sides by -1:

px - 2 = -9

Add 2 to both sides:

px = -7

Divide by p:

x = -7/p

p is a real number coefficient, which means it can be any kind of fraction, decimal, or integer as long as it doesn't contain any imaginary part, i.

So, we have x = -7/p.

Answer:

(2,5), (2,7)

Step-by-step explanation:

Because all prime numbers besides two are odd, and and odd number plus an odd number is an even number, there should be no solutions, unless, one of those numbers is not odd. In this case, there is only one non-odd prime number, that being two. So now that you know that one of the numbers is two, and has to be two, you have a little space finding the next number. The only restrictions its that its prime, if you add two you will get another prime number, and if you subtract two you will also get a prime number. In this case, both five and seven work. Some may say that three also works, but if you subtract two from three you get one, which is considered a special number, along with zero. Hope this helped! :D
